| Subject: | Molding leather help needed |
Thanks Larry. Are you talking about using a heat gun on dry or wet leather?
I hadn't seen that. Does it work like vinyl? I've thought about sewn seams
(I've got a machine for upholstery - still learning that too) but am
concerned about the multiple thicknesses. Since it's going to be glued down
I thought about butt-joint seams but wonder if they will lift or
swell/shrink over time. So many questions... Thoughts anyone?
Regards,
Greg Young

Greg, If a good heat gun and some stretching in the area of the recess in
the center aren't enough to get the material to lay flat you could cut a
horizontal relief in the material in the area of the cables and cover the
cut with a separate leather wrapped overlay of thin aluminum. Matching vinyl
material if available would be more pliable then leather. If you make
pattern out of vinyl a local upholstery shop should be able to sew the
material for a custom look but you have to be careful where you put the seam
to keep it out of the way.

There has been many questions as to where this property is, so I'm posting it here.
You can see it on Airnav, and on a Phoenix Sectional. It's 29.6 NM from
the TUS VOR on the 319 radial.

That's because 'active', in this case, refers to the fact that there's
electrically powered circuits (in this case an amplifier) in the antenna
to increase it's signal-to-noise ratio. The GPS antennas, however, can
be swamped by being placed too near a transmitting antenna.

Well, that's because there isn't any. Mounting receiver antennas in a
close group and transmitting antennas in a close group usually (never
say never) will not have any negative impact. Mixing them close
together probably will.
Also be aware that some Narco (don't know about others) radios are so
poorly shielded that when tuned to some comm freqs will kill the GPS
signal. You don't have to transmit ..... just being tuned to the freq
will cause the problem.

To the RV-6A builder with the clearance issue (sorry, I deleted the original
message):
I checked my aircraft today and you should not be having an issue. I think
the others who have replied to the effect of 'cut or file for appropriate
clearance' are misunderstanding that the F641 is the tunnel cover / seat
skin. However, in their defense, it's hard to see how you'd have clearance
issues with the F641 without also having clearance issues with the F605 and
F606 bulkheads; I definitely had to do some trimming there when I fitted
mine. However, that doesn't really address your problem, so I played around
with my setup and I think I may have an idea of what is happening; you will
have to confirm or deny.
If I disconnect the rear pushrod at the transfer bellcrank, I can get close
to the same interference (actually, I end up rubbing on the F605 bulkhead
first) as the stick approaches the F604 bulkhead (which has been trimmed per
the plans). I think this is what you are seeing. However, with the rear
pushrod attached (and the elevators in place, etc.) the elevator stops
prevent me from moving the stick that far forward and there is no clearance
issue. The stick is then approximately 7/16" from the front of F604 on my
aircraft. Also, when the elevator is neutral, the upper portion of the
stick should be perpendicular to level; if you make the lower portion
perpendicular instead, then the stick will be canted too far forward and you
may, again, have some clearance issues. The key here is to start at the
back; install the elevator, rear pushrod, and then install the stops, making
sure you get full movement of the elevator. Then set the elevator to
neutral and attach the rear pushrod to the transfer bellcrank, adjusting to
make sure the bellcrank is vertical. With the elevator still held in
neutral, make up the forward pushrod from transfer bellcrank to stick
assembly, making sure the stick is vertical fore/aft with the elevator
neutral. At this point, check the motion of the pushrods for clearance. I
think you will find it works fine.
If that is basically what you have done, then you will need to recheck
everything: height and orientation of the transfer bellcrank, height and
orientation of the stick assembly mounts, and even the stick assembly parts
(in case Van's made an error). Hopefully, this note finds you already with
a solution in hand.

My copy of the book came just a couple of days ago. It's really packed
with information. I can easily see why it took so long to write - it
will probably take me about a year to read it!

Charlie, lemme disagree here. Almost all (never say 'all' or 'never')
active antennas are receiver antennas. Such as those with a preamp,
like the GPS antennas we're talking about here. Almost all (same caveat
here) transmit antennas are passive. There are exceptions to both these
categories, but none apply to aviation AFAIK.

True .... good examples of passive receiver antennas.

And passive receiver antennas too.

| Subject: | Seeking good and bad experiences with Plane Power, B&C alternators |
I'm thinking of buying either a 60 Amp alternator made by either Plane
Power ($375 including internal regulator and OV from Van's) or B&C
($595 + $228 for regulator & OV = $823) for my RV-10. The Plane Power
price and simplicity are quite appealing. I've heard good things about
Plane Power, and have heard of only a single failure in the field. B&C
also has a very good reputation. So I'm seeking experiences, both good
and bad, from people who have put a few hours on a Plane Power (or B&C)
alternator.
Thanks,
Tim Lewis

I have two B&C alternators... one 60AMP and one 20AMP on the vaccuum pad.
They just work ! No problems so far.

B&C 60 A alternator and B&C regulator. All the problems that I have had (3)
are from wiring problems that were MY problems. Twice I had a bad
connection and one was a wire that had the insulation rub off and
intermittently shorted to ground killing the alternator output. B&C
troubleshooting guide that they have on their web site was used to find all
the problems that I caused. Problems that I caused were spread out over
almost 10 years. I made the airplane's first flight in September 1997.
B&C alternator and regulator has had no problems in almost 10-years of
operation.
